Air inlet 1/4 GAS; Ø inside tube min. 8 mm.
* Noise emission levels determined by using ISO/CD 15 744
The data are obtained with a supply pressure of 6 bar and an air flow equal to or greater than the consumption level
indicated.
NOISE
The table of technical specifications indicates the noise level- where the noise level exceeds 85 dB (A) the noise power is
also indicated. Ear protectors must be worn where the noise level exceeds 85 dB (A) at the operator position. We
recommend that you also wear ear protectors below this noise level.
Noise risk and hearing damage are related to the intensity of the noise source and the length of exposure. Noise risk
must be assessed on a case by case basis taking into account these two factors. Measures should be taken against
hearing damage in accordance with current Health and Safety regulations.
CALCULATION OF THE PERMITTED MAXIMUM RADIAL AND AXIAL LOAD OF MOTOR MVR(H).
Bearing 6202: C=7800 N, C0=3750 N.
Bearing 6000: C=4620 N, C0=1960 N.
Using the formula for dimensioning the bearings, the result is:
L10=(C/P)3 , where L10 = duration in millions of rotations
C = dynamic load coefficient
P = equivalent dynamic load
on bearing.
Taking the number of cycles before failure as 10 million, the result is:
10=(4620/P)3, where P=2144 N.
Final result: Fr = 1050 N
(maximum radial force in the absence of axial load).
The maximum axial force in the absence of radial load is:
Fa = 1850 N
